Grub VGA Modes


Posts: 228

Hello Group:

I would like to know what " MODE # " I can replace in Grub in the line that says, " vga=788 ".?? I would like to use a 800 X 600 mode.

I have put in the following, " vga=normal xref=800x600 ".?? But I am not sure if I actually am useing this or my input of " 0 " when I first booted up.?? There is a line in Grub that says " savedefault ", so I am not sure what is being used.

Here's a table showing frame buffer vga modes:


Color depth | 640x480 800x600 1024x768 1280x1024
-----------------+-------------------------------------
256 (8bit)| 769 771 773 775
32000 (15bit)| 784 787 790 793
65000 (16bit)| 785 788 791 794
16.7 Mill.(24bit)| 786 789 792 795


The vga= setting only effects the frame buffer, not X (unless you're using the fbdev driver in X). This'll mean that your console will display at this resolution.

Changes to the X resolution can be made in /etc/X11/XF86Config-4.

savedefault is used to make the default boot option the one last selected. e.g. you select "Windows" when booting, on the next boot "Windows" will be the default.
